Specially Designated Nationals List (SDN)
OFAC SDN List and XSD
As part of its enforcement efforts, Office of Foreign Assets Control (OFAC) publishes a list of individuals
and companies owned or controlled by, or acting for or on behalf of, targeted
countries. It also lists individuals, groups, and entities, such as terrorists
and narcotics traffickers designated under programs that are not
country-specific. Collectively, such individuals and companies are called
"Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S.
persons are generally prohibited from dealing with them. Click here for more
information on Treasury's Sanctions Programs.
